i'm getting estimates for a central AC system.

one estimate involves installation of an 'Aprilaire' (or similar) filter,
which is a heavy duty type AC filter that needs element replacement once a
year.

has anyone had experience with this type of filter?? is it worth the extra
cost??



Do the math, cheap filters go for about $3.50, $11
for standard filters that you change every 2-3
months under very bad conditions, so $44-66 per
year. What is the capital cost and the annual
replacement of the Aprilaire type. If the
Aprilaire type costs more for the first 8 years of
operations than the $11 filters, then go with the
$11 filter types. Just a thought!
